Volatile Mix

5-point evocation (fire)
Casting time:	action
Range:	60 feet
Components:	S, M (alchemist's tools)
Duration:	10 hours

You prime a potent mixture of alchemical ingredients in a vial, which you set or toss onto any unoccupied space within range. The vial is an object with 10 AC, 1 hit point, and immunity to psychic damage. Within the duration, if the vial is reduced to 0 hit points it blossoms into a thunderous, flaming explosion and the spell ends. You can choose to reduce the vial to 0 hit points on impact when you toss it. Within the duration, you can also use you action to instantly reduce the vial to 0 hit points, regardless of distance.
 Every creature within a 30-foot radius of the vial when it explodes must succeed on a Dexterity saving throw or take 4d8 fire damage and become ignited for 1 minute, and succeed on a Constitution saving throw or take 4d8 thunder damage or become dazed for 1 minute. If a creature succeeds either save, it takes half the corresponding damage and doesn't suffer the associated condition. Any creature reduced to 0 hit points by this spell is vaporized into ash, leaving no corpse.
 If this vial isn't reduced to 0 hit points by the time spell ends, the mixture becomes inert, rendering object no different than a common vial full of dirt.
 Ultimate Spell. Once you cast this spell, you can't cast it again nor cast any other ultimate spell until you finish downtime.
